Girls stop growing boobs as they finish puberty, typically between the ages of 17 and 18. However, it's important to note that breast size can change due to various factors such as weight changes, pregnancy, and hormonal fluctuations throughout a woman's life. The initial growth spurt of breasts is linked to puberty and the start of menstruation. After puberty, the overall size and shape of a woman’s breasts may continue to change, but the major phase of growth is typically completed by the late teens.
